As an example, in this work, assume that in our system we have 3loads (LD LD LD ,,) 123 and at a specific instant t each one has a probability (Pr Pr Pr ,,) 123 of being activated and to consume (Pl Pl Pl , , ) 123kW. Also for each load we assign a variable (Im Im Im ,,) 123 that denotesits importance, which is between 0 and 1. In this scenario at instant t wecan have the following events with their corresponding probabilities,Table 1.
